I'm trying to reduce as much as I can my VB.Net assembly side, and I just figured out that all variable names were kept unchanged in the actual assembly. Since I tend to use pretty long var names, it adds up and, by running dotfuscator on my assembly, I could shrink it by as much as 10%.

I am doing work for a client who has lost the source code for one of their VB.Net WinForms applications. The assembly they have is not obfuscated at all. I am trying to recover as much of the source as I can as C# source and have tried several tools for decompiling assemblies, including Reflector, ILSpy and JustDecompile (all the latest versions), but they all produce code with a huge number of errors in them. Because of the large number of errors in the generated code, I am going to ask about the specific errors (in different questions), get more directed answers and in this way try shed some light on why all the tools are having difficulty decompiling this assembly. This question pertains to the fact that the code generated by all these tools always have a large number of invalid member variables (fields) such as the following:
private short $STATIC$Report_Print$20211C1280B1$nHeight;
private ArrayList $STATIC$Report_Print$20211C1280B1$oColumnLefts;
private StaticLocalInitFlag $STATIC$Report_Print$20211C1280B1$oColumnLefts$Init;
why the generated code has these invalid member variables?
I am looping through a collection of items. Within that loop I need to set variables but they need to be a variable. I tried using lists but for some reason they don't get set properly. Heres what I have so far...

im pretty much a beginner to using ASP.net and linq to sql but what im trying to do is update a column of a table based on a variable. at the momment i have
Dim db As New sqldcDataContext Dim update As tableName = (From i in db.tableNames _ Select i)
i think this selects everything, how could i have two variables, one to store what table to update and the other what column. is this possible?edit: sorry for being unclear im trying to make this as dynamic as possible so i dont have to type in the exact table/col names. something like this but in the linq to sql syntax.
mysql_query("SELECT * FROM ". $table ." WHERE `" . $column . "` = "" . $data ."");
Given the following code:

Are there any side effects to naming the two exception variables the same or should they have different names?
how do I DIM a variable's name using previously declared string varialbes? I have been using PERL for processing data stored in text files but I now have a business need to use VB2008. I would like to do something like this:
dim name1 as string = "ABCD"
dim name2 as string = "123"
'here is the part that I don't know how to do - create a 3rd variable name concatenated from name1 and name2:
dim string.concat({name1,name2}), or maybe use a counter in a line like 'dim namex as string' with x being a counter value.
Essentially I want to dim variables using text strings extracted from a file. In PERL I have declared literals and arrays, such as 'my @$name1', which creates an array named with the contents of $name1. In VB2008 I am not sure how to make this work with the DIM statement.
Trying to understand the best way to do this and I'm can't get it figured. Here's basically what I have:
Public Class CardParsingClass
Private iAcctIDStart as integer
Private iAcctIDLength as integer
[code]....
I've only included 2 of the class level fields here but there are actually 30, so that's why I was hoping to be able to send the name of the field to set and the value to set it at in the SetValue function. So in some other routine in the program I'd like to be able to issue the following call:
SetValue("iAcctIDStart", "3")
But then when I get into the SetValue routine, I'm not sure how to proceed. I thought about a case statement that would basically be this:
select Case strFieldToSet
case "iAcctIDStart"
iAcctIDStart = cint(strValue)

I'm using a Microsoft Word form template to create objects in a form programatically, so depending on the information read by the program from the template.
So, I've got some fields where I store formula data for the form, in which I specify that the value for that field is obtained by multiplying other fields in the template. So I store in the string something like this:
"Text1.Text * Text2.Text"
So I need to convert these string values into variable calls to actually operate these values.
I'm looking to create multiple variables based on a counter object. For example if a counter object is 6 I want to create 6 instances of the variable mText
Something like:
Dim i as integer
Dim Count as integer = 6

Is there any way to access your variable names at runtime? Is there any kind of collection you can loop through?
View 2 Repliesthis website seems great and this is my first post. Sorry if this has already been answered but I have been searching for a long time. I have a program with a list view in details mode. I have it load column settings (visibility, display index, width, etc.) when the form is opened and save them when closed. There are many columns...about ten so far...like folder, file, size, etc. Is there a way to access variable names from the values of other variables?

I'm quite new to Visual Basic - using Visual Studio 2008 and can't seem to find a way to do the following:
I have a few tables in a SQL Server database and have used LINQ to SQL to create classes of those tables.
Here's a cut down example of what I'd like:listbox1 filled with table names - APS, SMPS, WCPC, CFLAPS
Then from the SelectedIndexChanged event, listbox2 should populate column headers of the selected table.
I have no issues getting data from the database, and can access all of these headers through the anonymous type objects created from a LINQ query (eg APS.ID, APS.count etc), but populating a listbox with these variable names rather than the data inside them seems rather elusive.
This is probably a cross platform coding question rather than VB specific, so if you have a solution in C# or whatever I'd be happy if you could let me know.
I am working on a project where my class has to execute VB code provided by the user, to make it simple I am trying to recreate my own eval function, I am using the following code I found on the web to do this task.

The problem with code is that it can't access any variables or there values, so I have decided to get the variable names, there values types and there types dynamically and recreate them in the class that is being created dynamically. Any way to get the variable names there types and values in the current class or method, so that I can recreate them, and execute the user passed code, the user knows what variables are in the current class or method and there datatypes but he don't know there values as they may have changed, so he can't initialize them. Is there a way to do this, this code will be called in an asp.net page on page_load event, the code passed by the user is stored in the variable vbCode that is passed as a parameter.
I am upgrading a VB6 to VB.NET project using the upgrade wizard.I know this is going to give me a lot of grief, but I am trying to make the old application useable. I'd rewrite it if I had time but am currently finishing up a summer internship and would like to get something working.One thing the wizard is doing that I can find no justification for is renaming of random variables. [code] For the life of me I don't understand why this is changing left. It isn't a reserved name as far as I can tell, there is no other variable named left that I can find in scope, and renaming it does not create a compiler error. [code] It does this to seemingly random variables throughout my project. Anyone have ideas as to why it doesn't like some of my variable names?

View 4 RepliesI'm essentially re-learning VB for the first time in 15 years to try and accomplish this task - I have a project to do for work which involves taking .doc files which contain hundreds and hundreds of names, addresses, e-mail addresses, and amounts they donated to the non-profit I work at, and inserting them into Outlook's contacts. I'm trying to piece together the bit I've figured out about Outlook/VB integration to do so, but unfortunately, most of the information I can find is the other way around - getting info FROM Outlook and inserting it elsewhere.
The doc file is essentially formatted like this:
FirstName LastName
423815 Central Park West
FirstNameLastName@Somthing.com
$3000.00
And repeat.
So for the email addresses, I obviously need to look for the @ and copy from the previous space or line break to the next - that's the theoretically easy part, along with the money donated, since I can similarly look for the $. The part that I forsee stumping me is, how to discern first and last name, and treat them accordingly, entering them into the right fields in Outlook? Same with the address.
I'm writing a small program that loads a folders contained file names into a list box, you then double click one of the file names listed and it appears within the programs text area where the user may freely edit it. I then have given the users options to export the data contained within the text box to a word template. What I'd like to do is add a button which the user can click in order to strip away all the html within the text areas content. I found a solution but for some reason I can't make it work. There are no errors displaying nor does the program crash out, it simply isn't doing what it should be doing.
The function I'm using is below:
Function stripHTML(ByVal strHTML)
'Strips the HTML tags from strHTML using split and join
'Ensure that strHTML contains something
If len(strHTML) = 0 Then
stripHTML = strHTML
[Code] .....
I've used the below snippet in an attempt to put the function to work in the text box.
Private Sub btnHTMLstrip_click()
' calls function stripHTML, applies to text box
richTxtBox.Text = stripHTML(richTxtBox.Text)
End Sub
So, its not working as it should?

I have started working on a legacy project (ASP.NET 1.1) which was done in an old machine (which I dont have access to). And I am unaware of the development environment settings used for building this project.
Nonetheless, I am able to build the project and deploy it all well from my machine (I created the full development enviroment locally). In my machine everything works great.But some screens where one of the assembly dlls (third party dlls) are used do crash on any machine other than mine! They probably do net get the proper assembly (with matching version or something), even though when I have put all the assemblies in bin (and used the same files while adding references to the project). .NET runtime probably tries to find them in the GAC of the other computers? Or probably in my system itself it loads from GAC and not from the bin? How could I know all this? The question is it runs perfectly fine on my machine, where the assemblies are at both places - in bin and in GAC.
I am lost what I should do to so that no matter which machine I deploy the project, it should always look in bin only! Also, I dont want to change the code in any way because its a legacy code and has been working all right since ages! Just some settings e.g. maching.config or soemthing?
